Richard Mille releases RM 30-01 Automatic with Declutchable Rotor

The latest model from Richard Mille merges timeless tonneau-shaped aesthetics with advanced mechanics. Featuring an easy-to-use but complex calibre, the RM30-01 sets itself apart with a energy-optimising declutchable rotor and an oversized date display.


ith the new RM 30-01 Automatic with Declutchable Rotor, the brand is demonstrating its ability to generate intense emotion stemming from the excellence of its technical expertise. A meticulous inspection of its double dial combining titanium and sapphire sets the tone.

Like its predecessors, it benefits from the aesthetic solutions and technical advances that are adopted with each new design. But far from forgetting its roots, the RM 30-01 is strengthening them through a reinterpreted skeleton design that helps to establish graphic balance. The grade 5 titanium bridges and baseplate create perspective and depth through the multiplication of their parallel segments.

The curves of the previous models have been eliminated to allow a diamond-based geometry to emerge that adds dynamic energy to the display of information. The power-reserve, clutch engagement and function-selector indicators thus benefit from an unprecedented arrangement, highlighted by coloured transfers for added emphasis.

In addition, the complexity of the new automatic RMAR2 calibre in no way precludes a certain aesthetic restraint, which helps to optimise its ergonomics and use. This kinetic sculpture is showcased by its components, such as the function-selector cam and oversized-date discs.

To remove any tension linked to winding, the RM 30-01’s variable-geometry rotor automatically declutches once the power reserve reaches 55 hours by disconnecting itself from the winding mechanism.

It thus enables the RMAR2 calibre to operate when the barrel torque benefits from the best constant torque/power ratio. When energy starts running short as soon as the 40-hour power-reserve threshold is crossed, the rotor reengages to rewind the barrel spring. It also allows the oscillating organ to operate while delivering excellent chronometric performance. It is possible to observe these phases on the clutch engagement indicator located at 11 o’clock, which shows the wearer whether the rotor is operating in the winding phase (on) or is disengaged (off).

The function selector also facilitates everyday life by allowing the owner to choose their desired mode by simply pressing the pusher at 2 o’clock. The indicator positioned on the dial above the oversized date informs them of the chosen option at all times: W for winding, D for date correction, and H for setting the hands.

Two variations of the watch highlight the sculptural tonneau-shaped case. One features a case back and bezel in 5N red gold teamed with a case middle in grade 5 titanium, while the other is entirely machined in this hypoallergenic material, which boasts exceptional resistance to corrosion and shocks. Its weight, which has been reduced as much as possible (to 96 grammes including the strap), and its ergonomics contribute to its remarkably comfortable feel on the wrist. Whatever version is selected – whether it is the grade 5 titanium timepiece or its counterpart in 5N red gold combined with grade 5 titanium, both beautifully enhanced with the same finishes (satin-finished, polished bevels, etc.) –, the taut lines and complex geometry of this case make it one of the most difficult to develop and produce in the entire watchmaking industry. The RM 30-01 thus inherits the artistic and technical options that have been developed with such rigour by Richard Mille.

A true synthesis of the identity of its collections, the RM 30-01 stays true to Richard Mille’s key values: ergonomics, pure lines and exceptional finishes. The RM 30-01 Automatic with Declutchable Rotor epitomises not only the quintessence of the brand, but also the many aesthetic adventures experienced by Richard Mille for over twenty years.

CALIBRE RMAR2: Skeletonised automatic-winding movement with hours, minutes, seconds, oversized date, function selector, clutch engagement and power reserve indicators and a declutchable variable-geometry rotor.

CASE DIMENSIONS: 42.00 x 49.94 x 17.59 mm


Circa 55 hours (± 10 %).
The power-reserve indicator is located in the upper-left corner of the dial.

These components in grade 5 titanium with grey electroplasma treatment provide the whole assembly superior rigidity as well as precise surface flatness, which is essential for perfect functioning of the gear train. The skeletonised baseplate was subjected to separate and extensive validation tests to ensure it met rigorous optimal strength requirements.

Semi-instantaneous, placed in a horizontal aperture at 4 o’clock.

In a manner similar to a car’s gearbox, a push-button located at 2 o’clock allows one to select the hand-setting, date-setting and winding functions with a simple push. A hand at 3 o’clock displays the selected function.

This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shock and during movement assembly or disassembly, hence better chronometric results over time. The regulator index is eliminated and a more accurate and repeatable calibration is possible thanks to 4 small adjustable. weights located directly on the balance.
